lNK-ERASER.

SPECIFICATION forming part of Letters Patent No. 486,976, dated November 29, 1892.

Application filed October 5, 1891.

To all whom it may concern.-

Be it known that I, J. ERWIN MAYHEW, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements Applicable to Ink-Erasers, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same, reference being had to the accompanying drawings wherein Figure 1 is a View of an ink-eraser embodying my said improvement. Fig. 2 is a flatwise view in front or rear, both being alike, of same device. Fig. 3 is a view of a portion of same device in central longitudinal section on plane mar. Fig. 4-is a view of one side of same device, the side on which the sleeve is split or slitted. Fig. 5 is a view of the opposite side of the same device. Fig. 6 is a view of the sheet-blank in outline, which is subsequently folded to form the sleeve. Fig. 7 is a view of the same blank shown in Fig. 6, with the springs cut and formed.

The letter a denotes the stock, preferably of some suitable hard wood, with sides that converge gently toward each other, so that the stock increases in size from the edge (a dull edge) upward, and this stock is provided with a handle 1), whereby to grasp and use the device.

The letter d denotes a pliable strip-for the purpose of an ink-eraser, preferably a piece of emery-cloth, which is folded over the edge of the stock and held in place so long as it remains fit for use by the sleeve 0. The sleeve is made of sheetmaterial,preferablyof sheet metal. Its first form,a sheet-blank, is shown in outline in Fig. 6, having certain cut-away spaces 0.

This blank is folded on the dot- Serial N0- 407,'708. (No model.)

ted lines into hollow form, producing the sleeve 0. The letter c"denote springs, which may be cut from the body of the blank, if the metal is springy, which it preferably is, and they are formed at the ends into spurs c'. The springs c (of which there may be one or two, but preferably two) bear on the sides of the stock and tend to make the hold of the sleeve on the stock secure. To further the same end, the stock is provided with mortises a. to receive the spurs c, which are, however, raised out of the mortises when the sleeve is pulled firmly in the direction which tends to pull it off the stock.

I claim as my improvement- 1. The combination, with the stock a, increasing in size from the edge upward, of a sleeve 0, formed with slits c and springs c", and the strip cl, substantially as described.

2. In combination, the strip d, the stock a, provided with mortises a, the sleeve 0, conforming generally to the shape of the stock and provided with the springs c, and spurs c, all substantially as described, and for the purposes set forth.

3. The combination of stock a, pliable strip 01, and folded slit sleevec, all substantially'as described, and for the purposes set forth.

4. The combination of stock a, pliable strip (2, sleeve 0, and springs c", all substantially as described, and for the purposes set forth.

5. The combination of stock a, pliable strip d, sleeve 0, and springs c", terminating in spurs c, all substantially as described, and for the purposes set forth.
